Merit Brass 4524-6000 Ss Pipe Nipple 1-1/2 in Sch 80 Gr 304

Product Description

The MERIT BRASS 4524-6000 is a seamless stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Built to Schedule 80 wall thickness, this nipple delivers greater pressure capacity compared to Schedule 40 equivalents, making it well-suited for demanding service conditions. Constructed from Grade 304 stainless steel, it provides strong resistance to corrosion and oxidation. Licensed plumbers and pipefitters install this fitting where a reliable, tight-tolerance threaded connection is required at a 1-1/2 inch pipe size.

This pipe nipple is appropriate for residential and commercial plumbing, hydronic heating, process piping, and general industrial applications where Grade 304 stainless steel is specified. Its seamless construction eliminates weld seams, reducing potential failure points in pressurized systems. The 1-1/2 inch pipe size fits a wide range of standard threaded fittings, valves, and manifolds common in mechanical rooms and equipment installations.

Key Features

• Seamless construction — no weld seam for improved pressure integrity
• Schedule 80 wall thickness for higher pressure service compared to Schedule 40
• Grade 304 stainless steel for corrosion and oxidation resistance
• 1-1/2 inch nominal pipe size fits standard NPT threaded fittings
• Suitable for plumbing, HVAC hydronic, and light industrial piping

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1-1/2 inch NPT threaded pipe systems using Schedule 80 seamless stainless steel nipples.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC and ASME B31 piping codes. Shut off and depressurize the system before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded connections in stainless steel fittings, as galling can occur without proper lubrication.
